To all whom it may] concern:

Be itiknown that I, WILBUR L. WRIGHT, a citizen of the United States,residing at W'ashington' District ofColumbia, have invented certain newand useful Improvements in and Relating to Paper Mater-ial Receptaclesand'the' like; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to certain improvements in vessels or receptaclesmade of paper andthe like; and the objects and nature of myinventionwill be readily understood by those skilled in the art in thelight of the following explanation of theaccompanying drawingsillustrating what I now consider to he, the preferred embodiments fromamong other formations and arrangements within the spirit and scope ofmy invention.

An object ofthe invention is to provide certain improvements in the neckand mouth portions of bottles or receptacles made of paper or equivalentmaterial, for the pur-' pose of greatly increasing the strength andrigidity thereof without exposing the contents of the receptacle tocontact with other than the paper, or equivalent material, forming the.walls of the receptacle, and so as to provide the rec'e1' tacle neckwith a comparatively smooth interior surface without objectionableshoulders or recesses for the collcction of foreign matter orthe like.

vA further object of the invention is to provide a receptacle made ofpaper or equivalent material with, an improved stiffening neck ring and"in so applying and fastening the paper material forming the bottle tosaid ring as to cover the ring from contact with the contents of thebottle while fillin and emptying, and to provide means for e fectivelysecuring or looking closures over thenece tacle mouth.

The invention consists in certain novel features in construction and incombinations and arrangements of p rts and elements as more fullv andparticu arly set forth hereinafter.

Referring to the accompanying drawings;-Figurei 1 is a.per's'pectiveview of the mouth or neck portion of a paper receptacleformed in accordance with my invention, a closing disk providedQwith aull tab or handle being shown seated on t e internal .seat or shoulderof the receptacle mouth to seal the same. Fig. 2', is a vertical sectionthereofj! Fig. 3, is awertical section thr'ou' h theneck portion of thereceptacle and t e neck ring, dotted lines indicating the form of thereceptacle neck-when first inserted through the neck ring. full linesshowing the form assumed-by said neck after'being spun or pressed downon the neck ring to form the receptacle mouth, the neck ring be ingshown dropped from proper position in said mouth. and in itsoriginalform before its outer upwardly extending flange ha'sbecn spun orpressed in to lock or securethe depending paper edge of the neck toth'e'neck ring. Fig. 4., is a vertical section showing.

an outside paper cap or closure sealing the receptacle mouth and securedby having its depending annular flange spun 11 under the outer dependingportion of t e neck ring. Fig. 5, is a vertical section showing amodified formation of the neck ring and to be spun down on the outeredge of a closing cap for securing the same. Fig.6, is a vertic'alsection showing'm'y receptacle neck or mouth formation with the cap orclosure of Fig. 7, applied thereto. Fig. 7 is a detail perspective viewof an exterior or cover-all cap particularly adapted for application andlooking on receptacle mouths of my formation. *ig. 8, is a verticalsection of a modified construction. Fig. 9, is a perspective view of areceptacle mouth or neck portion' of my invention of a square or angularoutline. Fig. 10, 'is a vertical section showing a modified formation ofneck ring and bottle mouth.

It is'the purpose of m invention to provide rece tacles made 0 paper orthe like with sti ening neck rings to which the paper material issecured and which is' covered by the paper material usually at the topand interior of the receptacle mouth. To this end I provide a. metalneck ring or annulus approximately of an inverted U- shape in crosssection to form an annular top-wall hollowbody or surface 1'. This ringis formed with the short flat annular flange 10, extending inwardly fromits lower inner edge, and with the securmg flange 11, extendingoutwardly and then upwardly from its outer lower'edge. The hody of thepaper material receptacle 2, is suitably formed with 'an elongated neckportion 2 which is passed through the open center of the neck ringso asto project the desireddis tance beyon the same, as indicated by dottedlines Fig. 3. Suitable "mechanism is then applied to the extended neck2, and to the portion of the paper material within the ring to spin orpress said neck down onto and over the ring and tightly to the interiorand top surfaces of the ring with the outer edge 21, of the paper necktightly fitting and depending at the outer surface 1, of the ring andwithin the securing flange 11. A suitable spinning or other tool thentightly presses the flange 11, inwardly tofirmly lock and grip the edge21,-of the paper material between the body 1, of the ring and the flange11, as clearly shown by Fig. 2. While these operations are per: formedthe paper receptacle is firmly held and backed by suitable cores andforms and the neck ring is held and backed by suitable devices.

The paper is spun and pressed over and tightly to the neck ring to formthe paper material top edge 20 of the bottle mouth usually by suitablehot dies which cause the paper material to accurately, smoothly andtightly conform to the neck ring and permanently maintain suchconformation for the purposes intended.

-The paper material passes over and is spun or pressed to closelyconform to the inner flange 10, to form the internal closing cap or diskreceiving shoulder or seat 22, within the bottle mouth to receive aninternal closing disk, for instance, such as 3, Figs. 1 and 2. This flatpaper material sealing'disk 3, is pressed into the receptacle mouth tofit said shoulder and close the receptacle, as will be understood bythose skilled in the art. T-show the disk provided with a pull tab orhandle 30. whereby the same can be lifted fromthe receptacle mouth. Thistab is formed'by a small piece of flat wire resting horizontally on thetop face of the disk with its outer end 31, passed down through the diskand clenched, while its free end is formed with a perforation 32,

to form a grip when the free end of the wire is bent disk.

Tn Fig. 4:, I show the receptacle sealed byan exterior or cover all cap4:, fitting and conforming to the top edge 20, of the receptacle mouthand having an exterior annular depending flange 40. extending down atthe exterior of the bottle mouth and neck ring flange 11, and secured byhaving its lower edge 41, spun or pressed inwardly around the lowerouter edge of the neck ring and upwardly into the recessed under portionof the ring. A permanent or sealed cap is thus provided which cannot betampered with or removed without destroying the cap or leaving clearevidence of the fact that the cap had been removed and reapplied. Suchan up and grasped to pull out the arrangement and provision is ofpeculiar utility particularly for milkand cream bottles or likereceptacles. y

In Fig. 5, I show the securing flange 11, of the neck ring formed withan upwardly and outwardly flared cap-securing annular extension 12. Ishow an exterior cap 5, closing the receptacle mouth and fitting down onand conforming to the top edge thereof and formed with a short annulardepending flange or edge 50,- within the ring flange extension 12, sothat the cap can be secured by spinning or pressing the flange 12inwardly and down on the cap flange 50, as indicated by dotted linesFig. 5,'or the trough formed by the upwardly and outwardly flaringflange 12, and the cap flange 50, can receive paraflin for the purposeof securing and sealing the paper cap.

In Figs. 6, and 7, I show an exterior or cover all paper cap 6, havingan annular depending flange 60, to which are secured several thin flatmetal wire strips 61,"s0 that their free ends depend therefrom. This canis adapted to fit over the bottle mouth as shown in Fig. 6, and 'besecured by bending the lower or free ends of the metal tabs or strips61, inwardly under the lower outer edge of the. neck ring and thenupwardly within the bottom recess of such ring. This arrangementprovides whatis practically a permanent seal in so far as the cap cannotbe readily removed without lnjuring or destroying the same, the bentends of the metal tabs being concealed and practically inac cessibl'e.

In Fig. 8, I show a construction wherein the 'eXteriOr or cover allclosing cap 7, is formed with an exterior dependingflange 7 0,permanently secured to the bottle mouth by the neck ring securing flange11. with the outer edge 21, of, the paper material forming the bottle.This permanent cap is shown formed with a depressed center having asmall central opening 71, through which the receptacle can be filled andemptied. This opening is-adapted to be covered by a small disk 72, andsealed with paraflin 7 8, or the like deposited in the cen-- traldepression of the cap. l

It will be noted that a neck ring of the general type disclosed providesmeans whereby these various exterior caps can be easily and quicklysecured to the receptacle mouths and whereby cap locking or sealingmeans can be employed and important practical advantages are therebyattained It will also be noted, that the. neck ring pro .vides for thereception of inner closing disks or caps which can be employed with orwithout exterior or cover all caps.

Attention is particularly directed to thefact that my neck ring is soformed or arranged with respect to the paper material of the vessel asto be completely covered thereby in sofaras liability to comev in con.-tact with the contents of the receptacle is c n ned. Thisv is a featureof importance;

catch or retain foreign matter or any of the contents of the receptacle.

It will also be noted that the receptacle neck and mouth formation of myinvention is applicable to variously shaped receptacles whether round orsquare and to receive various closures and I do not wish to limit myselfto the use of the closures disclosed hereby.

The neck ring greatly stiffens and strengthens the receptacle andimparts the desired rigidity thereto and enables such receptacles to besuccessfully used in capping machinery for automatic application ofclosing disks. These neck rings can beemployed in small mouth bottles aswell as large mouth receptacles imparting the desired rigidity theretowith a minlmum use of materials and consequent economy in production,and without detracting from the general appearance of the product orresult ing in the production of receptacles of the freak type inappearance.

In Fig. 10, I show what is approximately a reversal of the constructionshown in the remaining figures of the drawing. In this formation thepaper wall 2, is drawn up at the outer side of the metal stiffening ring1, and over the top thereof and then down at the inner side thereof andsecured by spinning or pressing the inner upturned flange 1", of thering tightly down on to grip and secure the depending paper flange 2.The flange 1 has an inward annular bulge 2 to form theclosing-disk-receiving seat in-the bottle mouth. I
